In the home, cats have been beloved as pets for at least 4,000 years.  But out in the wild, felines can be ferocious predators, and according to E Magazine, concern is growing over the impact of these hunters on many less-stealthy species.  One particular place of note is Florida, where feral cats are taking quite a toll on native species like beach mice and marsh rabbits, as well as possibly spreading feline leukemia to the highly endangered Florida panther.  Some cat advocates embrace a trap, neuter and return policy to lower numbers, but with 48 million of America’s 70 million cats allowed outdoors, and 40 to 100 million more strays or wild, experts will surely be clawing for solutions to this growing fracas over felines.
